摘要:
A code acquisition device securing reliable code acquisition and reducing a time required for a code acquisition procedure. In the device, a sampler samples an input signal, and a searcher continuously searches for a spreading code used for the sampled signal until the phase of the spreading code is acquired. A verifier verifies whether the phase of the spreading code used for the sampled signal is acquired, according to the search result of the searcher. The searcher initializes and restart the verifier whenever the phase of the spreading code is searched.
